B'RIQUETING-MACHINE.

SEECIFIGATGN forming part of Letters Patent No. 678,359, dated July 16, 1901.

Application filed August 31, 1897. Serial No. 650,101. (No model.) l

T all whom it may concern:

Be it known that. I, JOHN THOMAS DAvIs, a citizen of the United States, and a residentl of San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Briqueting-Machines, of which the following is a specification.

My invention relates to apparatus for moldro ing, compressing, and forming'into briquets, eggettes, and other shapes culm or coal-dust and other material capable of being so treated the same being usually prepared by being mixed with some suitable binding material or substance. l

The invention consists, essentially, of the novel construction, arrangement, and combination of one or more series of molds for receiving the material to be treated, a toothed zo wheel or roller for compressing the molds and their contents, and other devices and parts more particularly hereinafter described.

. In the accompanyingdrawings, Figure 1 is a side View, partly in section, of a machine embodying my invention. Fig. Zis a transverse vertical section o'n the line'l'1 of Fig. 1, the said View also showing diagrammatically, in dotted lines, the action of the guard-opening roller hereinafter described. Fig. 3 is a 3o horizontal section of one of the molds open, with appurtenant parts. Fig. 4 is aback View showing one of the molds open. Fig. 5 is a side view, partlyin section, of a modified form of my invention; and Fig. 6 is a detail View 3 5 of the same.

The construction of my invention is as follows: To a suitable base or foundation A are bolted or otherwise secured upright supports B b b for the running parts of the machine.

4o Upon the supports b b are journaled rollers or drums C C', over which pass endless chains D, composed of links secured together in the usual or any suitable-manner. In the drawings but two chains are shown, (see Figs. 2

and 3;) but it is obvious that any number of chains and supporting rollers or drums may be employed, each pair of chains bearing between them a series of molds, as hereinafter described. 1 Y

o The molds for receiving and compressing the material to be treated are each formed of .two parts,'the form of which will of course vary somewhat, according to the shape which it is desired to'give to the finished product. In the accompanying drawings the molds are shown formed of two parts F. and F, hollowed out interiorly to form approximately hernispherical cups. The parts are pivotally united or hinged at their lower edges and secured by a pin or bolt G, the ends of which extend outward and secure the molds to the adjacent links of the endless chains, Figs. 1, 2, and 3. A spring g, which may pass around the projecting end of the pin G, acts upon the studs e andf to keep the molds open, except when the same are closed in the operation of the machine, as hereinafter described. The said studs also prevent the molds from opening too far by resting upon the top of the link, as shown in Fig. 1. The parts F of the molds are 7o provided with downwardly-projecting cams h, adapted toen gage with the roller H and be elevated thereby, as hereinafter described. f y

'I and J are lateral guards for preventing the Aescape of the material to be molded before the closing of the mold. The guard I is rigidly attached to one side of the part E of the mold while the guard .I is pivotally attached to the partF of the mold, as show-n in Fig. 4, orin an y suitable manner. The edges of the guards 8o do not meet at the top'of the mold; buta sufficient space exists between to permit the passagey of material into the mold. (See Fig. 3.) Both guards are shaped so as to embrace the sides of the part F of the mold (see Fig. 2) 85 and allow the same to move freely therein as the mold opens and closes, the said part F Vheingalso suitably shaped externally, having channels-or recesses f2, into which the edges of the guards pass, with a wider por- 9o tion f3 above for engagement with the teeth of the compressing-wheel, as hereinafter described". The guard J is provided with a spring K, wound around the end kof the pin of the hinge, attaching said guard tothe mold, the said spring serving to keep said guard closed except when opened,' as hereinafter described. The said guard .I is also provided with alaterally-projecting arm L, Fig.2,which when depressed opens the guard. Attached to the right-hand support b, Fig. 1, is a Wheel or roller M, placed so as to engage with the arm L when the mold passes by. The rela- IOO tive position of said arm and roller when engaged is shown in Fig. 2. The said View does not, however, indicate the true position of the roller with regard to the machine as a whole, said position being shown in Fig. l, Fig. 2 being, as regards the roller M and the dotted lines showing the open guard, a diagram matic view.

R is a toothed wheel or roller journaled in suitable upright supports, only one of which appears in the drawings, B, Fig. l. It is provided with teeth r, which are ot' such lshape and pitch as to readily grasp the molds, completing the closing thereof, which is begun by the action of the roller H upon the cams h, and when the molds have passed directly under the wheel tightly compressing the same, as shown in the middle part of Fig. l. The chains D, carrying the molds, pass in the upper part of their course over a table S, supported by shelves b2, projecting from the supports B. This table upholds the molds and reacts against the downward pressure of the-wheel R, thus allowing any desired degree of compression to be obtained. In order to obtain different degrees of compression, the wheel R may be journaled or mounted adjustably in any suitable manner to allow a slight vertical variation in its position. In the drawings the wheel R is shown comparatively narrow,` Fig. 2, and adapted to operate but one series of molds; but it is obvious that should it be desired to employ and operate two or more series of molds simulta neously the wheel R can be made of any width, forming in that case a roller, which could be either grooved continuously or provided with pockets suitablyshaped and situated to engage with, close, and compress the molds.

N is a hopper for receiving the material to be treated. It opens at the bottom over a measuring-roller T, which is provided with pockets t, each capable of holding the proper quantity of material to fill one of the molds. The measuring-roller is provided with a gearwheel or sprocket t2, over which passes a sprocket-chain 3, which also passes over a sprocket r2 upon the wheel R. The sprockets rz and t2v are so geared with reference to each other that the measuring-roller T shall make half a revolution while the wheel R moves one tooth, andthe relative positions of the various parts are so adjusted that when the measuringroller is in the position to discharge, as shown in Fig. l, an empty and open mold may be directly underneath to receive the material. Below the measuring-roller is a spout or guide n for directing the material into the molds.

The operation of my invention is as follows: Power from any suitable source is applied either to the drum or roller C' or the wheel R, or to both. The endless chains passing over the rollers being thus set in motion, the molds are successively carried into position below the measuring-roller T, being held open by the springs g, and arc filled with the material to be treated. Passing along, the molds are partly closed by the upward action of the roller H upon the cams 71, and are then grasped between the teeth 1^ of the wheel R and subjected to an increasing pressure, which reaches its maximum when the mold is directly beneath the axis of the wheel R. As the molds pass farther on and are released from the teeth of the wheel R they are forced open by the springs r and passing still farther, into the position shown in the lower right-hand corner of Fig. 1, the guard J on one side of the mold is opened by the action of the roller M upon the arm L and the completely-formed briquet allowed to escape, the same havingbeen until then held in the mold, the space between the top edges of the guards not being sut'iicient to allow it to pass. The operation of the roller M in opening the guard is shown by the dotted lines in Fig. 2, the said view heilig to that extent a diagrammatic one, as stated above.

Fig. showsa modicationot` my invention, and Fig. is a horizontal section of one of the molds ofsuch a modified machine,taken on the line 6 6 of Fig. 5. In this form of my invention the chain-carrying rollers, the compressing wheel or roller, and the devices for feeding the material to be treated to the molds are the same as in the form of the invention hereini before described. The endless mold-conveying chains also are substantially similar'. The molds, however, instead of being placed at or about the middle of the links of the chains are placed at the ends of the link, one-halt of the mold being rigidly attached on each side to each of the adjacent ends of the links, and the lower parts of the two halves F.2 and F2 of'each mold, as well as the links to which they are attached, being united in a common hinge-joint and secured by a common pin o1' bolt G2. In this form of my invention the springg and the roller Hand cam h may be dispensed with, as the passing of the chain over the rollers C C' will open the molds, and the straightening of the chains after they leave the roller C will close the molds sufficiently to allow them to be grasped between the teeth of the compressing-wheel. The side guards for the molds, with closing and opening devices therefor, will, however, be required in the modified form of my invention as well as in the form first described. These guards and devices are not shown in Figs. 5 and G, being substantially similar to those shown in the preceding figures. The operation of the modified form ot my invention is, with the exceptions above noted, the same as that" of the form first described. lt is obvious that in this form of my invention also any number ot series of molds and conveying-chains may be employed by increasing the length of thleI conveying-drums andthe compressingro er.

It must be understood that although I have products thereof briquets I do not confine my claims to machinery for manufacturing what are technically 1Known as briquets in the strict sense of the word. It will be obvious that the shape of the finished product is merely dependent upon the shape of the interior of the mold and that the machine and its operation will be essentially the same7 whether the products be such as are, strictly speaking, called briquets or they be eggets7 or any other shape into which such material may be formed.
